# Site configuration -- do not distribute this file.
# Based on the setting of environment variable `HDF5_MODE' we set the
# compiler flags unless they're already set. Its value can be one or
# more of the following words (be sure to use single quotes when
# setting its value or the dollar signs will be expanded as variables
# too soon):
#
# $warn -- Generates compiler warnings. You should always
# include this since it has no effect on the speed of
# the code produced.
#
# $debug -- Compiles in code to check for invariant conditions
# and turns on the `-g' flag for interactive
# debugging. It also turns off seek optimizations in
# the low-level file driver. This version of the
# library can be significantly slower than a production
# version.
#
# $production -- Compiles an optimized version of the library
# and disables code that checks for invariant
# conditions.
#
# $profile -- Compiles code with the `-pg' flag which
# produces a `gmon.out' file when the library
# runs. The gprof(1) command can read that file
# and produce detailed run-time statistics.
#
# If HDF5_MODE is undefined then we use the value
#
# $debug $warn -DH5F_LOW_DFLT=H5F_LOW_SEC2
#
# Unconditionally set the compiler to gcc since the following flags
# only apply to that compiler.
CC=gcc
